The Freyssinet stay cable has been improved since its first applications to provide better fatigue resistance and durability; at the same time, research has been carried out to transfer its benefits to other uses.
The Cohestrand® Cable was thus developed to meet the needs of suspended structures, in which the loads are transferred to the suspension cables by means of collars and hangers. In 2005, Cohestrand® was used on the Kanne Suspension Bridge (Belgium); it was later used in conjunction with deviation saddles on several cable-stayed structures, including the Tilikum Crossing Transit Bridge over the Willamette River in Portland, OR in 2012 and the I-35 Brazos River Bridge in Waco, TX in 2014.
More recently, Cohestrand® has found a new area of application in suspended stadium roofs, where it offers architects unique flexibility and lightness and building owners a 100-year service life.
